Application filed November 12, 1914. Serial No. 821,682.

Bloomington, in the county of McLean and' State of Illinois, have invented certain new and useful Improvements in l/Vrenches, of which the following is a specification.

The present invention relates to a wrench more particularly adapted to beV usedvby mechanics, etc., for th'eusual purposes to which the ordinary wrench is applied.V

The objects of the present invention are to so construct the head of the wrench as to permit the jaws thereof to be turned anf placed in any relative position of angularity desired with respect to the handle. j A further object of the invention is to provide means whereby the space between the jaws may be varied to permit application of the wrench to objects of various size. Further objects of the invention are to provide means for locking the jaws in adjusted position and to provide means for locking the head in turned position.

The invention further consists in the features of construction and combinations of parts hereinafter described and claimed.

In the drawings: Figure 1 is a side view partly in section of the wrench of the present invention showing by means of dotted and full lines the head turned to bring the jaws into different positions of angularity with respect to the handle and the jaws moved different distances apart to adjust the spacing therebetween; Fig. 2 is a plan view of the parts shown in Fig. 1;y Fig. 3 is a face view of that portion of the head carrying the fixed jaw; and Fig. 4 is a face view ofthat portion of the head carrying the movable jaw.

In the construction of the common form' i of wrench the head maintains a Xed position with respect to the handle and it is sometimes difficult, owing to its location, to gain a purchase upon the nut or other article being operated upon. In the type of wrench illustrated in the present application, the above difficulty is overcome by making the head so that it can be'turned into angular position with respect to the handle. 1n

order to make the wrench applicable for use upon various sizedV articles, it is frequently'necessary to change or adjust the distance which the jaws are spaced apart,

and the present invention deals with a means for accomplishing this 'end in conjunction with that type of wrench in which the head can be turned. v

Referring to the drawings, the wrench' consists of a handle 5 of any'suitablershape or size which terminates at its upperend in a fork 6 and mounted within this fork by means of a pin 6a, is the head 7 consisting of a part 8 yand a part 9. r1`he part 8 carries what may be termed the movable gripping jaw 10, and the part 9 carries what maybe termed the. fixed gripping jaw 11. The part 8-is formed for a major portion of its periphery with teeth 12' and the part 9 and 13 are designedv to aline with one another when the device isassembled and 'ar-" ranged to engage with said teeth is a springpressed pawl 15 mounted in the handle 5 'i (see Fig. 1). The handle is formed witha slot 16 through which extends a finger piece 17 ormoving the pawl 15 to bring it out of engagement with the teeth 12 and 13. 1t

lis obvious from the drawings that by releasing this pawl 15 the head is free to be turned to any desired position by releasing the finger piece 17 the spring of the pawl will act to force the pawl back into place and lock the head in turned position, so that by this means the head can be adjusted to any position of angularity with respect to the handle. v

As stated, it is necessary for practical use of the wrench to adjust the spacing between the jaws and forthis purpose one of the jaws carries a spring-pressed pawl 18 which is adapted and arranged to engage with the teeth 14 of the head 9 and a suitable finger piece 19 is provided for raising and lowering this pawl. Thus by turning the part 8 or part 9 and dropping this pawl into any of the teeth 14 desiredy it is obvious that thev spacing between the jaws can be regulated.

By arranging the teeth 14 so that they slope in an opposite direction from the direction of slope of the teeth 12 and13, the jaws jaw 10 by turning of the part 8 or 9 of the head does not place the teeth l2 and 13 out of alinement.

The terms fixed and movable jaws are used 'for descriptive purposes only, since both are in fact l'iXedly secured to that portion of the head with which they are asso` ciated.

By the above construction the head of the wrench can be turned to' angularly adjust the aws with respect tothe handle, and the jaws can be relatively adj-usted so as to vary the space therebetween and by these adjustments the wrench can be arranged to operate upon objects of different sizes and objects placed in a position which it would be ditlicult, if not impossible, to operate upon with that style of wrench in which the head is iiXed with respect to the handle.

The device is extremely cheap of construction and contains no involved parts which would become impaired by ordinary usage.

l claim:

l. In a wrench the combination of a handle, a head carried by said handle and adapted to be turned into different degrees of angularity with respect to said handle, said head consisting of two parts independently movable about a common center, a jaw eX- tending from each of said parts, the periphery of said partsbeing formed with teeth, means for engaging said teeth to lock the head in turned position, a portion of the teeth on one of said parts sloping in an opposite direction from the direction of slope of the remaining teeth, a shiftable member carried by one of said jaws and adapted to engage with the oppositely sloping teeth for locking the jaws in adjusted position with respect to each other, substantially as described.

2. In a wrench the combination ot a han dle, a head carried by said handle and adapted to be turned into different degrees of angularity with respect to saidA handle, said head consisting of two parts independently movable about a common center, a jaw extending from each of said parts, the periphery of said parts being formed with teeth, means tor engaging said teeth to lock the head in turned position, a portion of the teeth on one of said parts sloping in an opposite direction fromY the direct-ion ot slope of the remaining teeth, a. shittable member carried by one of said jaws and adapted to engage with the oppositely sloping teeth for locking the jaws in adjusted position with respect to each other, and all of said teeth being spaced apart an equi-distance, substantially as described.
